The federal government drew a chemical line through kratom, by potency, not a blanket ban.
DEA and HHS have moved to temporarily schedule concentrated 7-hydroxymitragynine while explicitly leaving natural kratom leaf alone, using a numeric potency threshold instead of a categorical ban. Where that threshold finally lands, and how it is measured, will determine how much of the existing kratom market ends up scheduled; the public comment window on it closed July 31.
